On the engineering of higher-order Van Hove singularities in two dimensions
Anirudh Chandrasekaran, Luke C. Rhodes, Edgar Abarca Morales +4
The properties of correlated electron materials are often intricately linked to Van Hove singularities (VHS) in the vicinity of the Fermi energy. The class of these VHS is of great…
Single monkey-saddle singularity of a Fermi surface and its instabilities
Ömer M. Aksoy, Anirudh Chandrasekaran, Apoorv Tiwari +3
Fermi surfaces can undergo sharp transitions under smooth changes of parameters. Such transitions can have a topological character, as is the case when a higher-order singularity,…
Resonant inelastic X-ray scattering in the topological semimetal FeSi
Yao Shen, Anirudh Chandrasekaran, Jennifer Sears +8
The energy spectrum of topological semimetals contains protected degeneracies in reciprocal space that correspond to Weyl, Dirac, or multifold fermionic states. To exploit the unco…
